Safety is important to a robot that is used in a way that can impact on the wellbeing of people. However, understanding and managing the safety information of a robot is not a trivial task. The quantity of this information is large, and it is usually stored in text-based formats. These factors mean that maintaining safety information when it changes is error prone, and understanding it requires manually...
Robots need to be dependable to work closely with humans. Further they must be accountable for the system design and development process. This makes some of the safety related standards such as IEC61508 adopt module based architecture and model driven engineering process. On the other hand, module-based architectures using middlewares are popular in the integration phase, when developing robot systems...
Recent years have seen an increase in demand for robots that work closely with humans, or operate at disaster sites. These robots need to have high dependability. At the same time, the idea of system development based on standards is becoming important especially in the field of embedded systems including robots. IEC61508, which is a standard of functional safety requires the V-model of the engineering...
The study concerns a 2D safety vision system for human-robot collaborative work environments. The vision system is characteristic of having a freedom from structuring the environment by setting passive markings, i.e. neither painting on the floor nor hanging a camera up on a ceiling is necessary. To preserve safety states, we set the passive markings in the original image based upon Shannon information...

With the increasing presence of intelligent systems such as robots in our everyday lives, the risk of a failure in one of these machines causing injury to someone is growing. No longer can we rely on training and fenced-off work cells to provide safety. Instead, we must consider other approaches to producing dependable intelligent systems. This includes revising how we design intelligent systems and...
